P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

Symport/Antiport P Systems with Three Objects Are Universal
(IOS Press, 2005)
The operations of symport and antiport, directly inspired from biology, are already known to be rather powerful when used in the framework of P systems. In this paper we confirm this observation with a quite surpris- ing ...

Spiking Neural P Systems: A Short Introduction and New Normal Forms
(Editorial Academiei, 2012)
Spiking neural P systems are a class of P systems inspired from the way the neurons communicate with each other by means of electrical impulses (called \spikes"). In the few years since this model was introduced, many ...

Spike Trains in Spiking Neural P Systems
(World Scientific, 2006)
We continue here the study of the recently introduced spiking neural P systems, which mimic the way that neurons communicate with each other by means of short electrical impulses, identical in shape (volt- age), but ...

Universal P Systems: One Catalyst Can Be Suficient
(Fénix Editora, 2013)
Whether P systems with only one catalyst can already be universal, is still an open problem. Here we establish universality (computational completeness) by using speci c variants of additional control mechanisms. At each ...

Spiking Neural P Systems with Several Types of Spikes
(Fénix Editora, 2011)
With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...

Polarizationless P Systems with Active Membranes Working in the Minimally Parallel Mode
(Fénix Editora, 2007)
We investigate the computing power and the efficiency of P systems with active membranes without polarizations, working in the minimally parallel mode. We prove that such systems are computationally complete and able to ...
